SPECIFICATION forming part of Letters Patent No. 705,897, dated July 29, 1902.

Application filed June 3, 1901. Serial No. 62,961. (No model.)

the following is a full, clear, and exact de-' scription.

This invention relates to an internal-combustion or explosive motor, the main feature of which lies in the provision of a receiver in which the charge is exploded and which serves to carry a continual pressure of gas,

this pressure being communicated from the receiver to the motor,which is driven thereby.

This specification is a specific description.

of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification,

' in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan View of an automobile vehicle, showing my invention applied. Fig. 2 is a side view of the same. tional view showing the receiver and the mixing and igniting mechanism of the motor. Fig. 4. is a cross-section on the line 44 of Fig. 3. Fig. 5 is a sectional view on the line 5 5 of Fig. 3. Fig. 6 is a similarview showing the parts in a different position. Fig. 7 is a plan view showing the pump and the gear operated thereby- Fig.8 is a side, elevation of the same. 'Fig. 9 is a sectional view'on the line 9 9 of Fig. '7. Fig. 10 is a view of This vehicle may be of any sort desired and may include a steering mechanism a, a movement transmitting and varying gear a and a brake mechanism a The engine comprises a receiver made up of two cylindrical sections band I), of which the former is mounted rigidly in the framing a or in any other suitable support. The lat- Fig. 3 is a sec-- ter section b is slidable in the section b, and its movement is guided by rods b fastened to the stationary section b. A cap 12 is attached to the rods b and this cap carries a pin bflwhich fits in a centrally-disposed socket b in. the-sectionsband carries an expansive spring .1), which presses the section I) inward and tends to contract the size of the receiver formed by the sections Z) and 1).

o indicates a pipe which passes from the section b of the receiver and communicates with the interior thereof. This pipe 0 extends to the motor proper, which comprises a suitable casing c',havinga wheel c ,mounted to turn around the axis of a shaft 0 from which shaft :the movement of the motor-is transmitted.

0 indicates the exhaust from the casing c, and leading from the pipe 0 are two branches 0 and c, which lead into the casing c at opposite sides of the axis of the wheel 0 Each branch 0 and c is fitted with a valve 0 these valves controlling the passage of the gases through the branch pipes. Connected with the valves 0 are rods c which lead to suitable hand-leversor other devices for actuating therods. By these means the valve 0 may be thrown to command the branch pipes c and c. If the valve of the pipe 0 is closed and that of the pipe 0 is opened, the wheel 0 will be driven from left to right. (See Fig. 10.), If the valve of the pipe 0 is closed and that of the pipe 0 is opened, the wheel 0 willbe driven in the opposite direction.

(2 indicates the tank containing the liquid fuel, which may be any of the Well-known hydrocarbons. From this tanke leads a pipe 6, provided witha valve (2 (See Figs. 3 and 9.) This pipe (2 passes down into a water-tank d, fastened to the stationary part b of the gasreceiver. WVithin the tank (1 the pipe 6 communicates with an air-pipef, which passes into the tankd from a pump f, mounted on top of the tank (1. Thepumpf has its rod f driven from the motor-shaft c by an eccentric or any other suitable means.

(1 indicates a valve chamber which is formed in the water-tank d. Into this chamher the pipe f passes, and the valve-chamber I f which are pivotally mounted on the slide section b of the gas-receiver.

and are so arranged that when moving in one direction they willact to transmit movementin a horizontal plane and when moving in the opposite direction they will turn on their pivots without transmitting any movement. The valve 6 has a stem 6 to which is pivoted a horizontally-disposed arm 6 projecting over the slidej of the pump. To the arm e is connected a cord h, which passes upward and is connected to a lever h, forming part of a safety-valve 71 the lever h being fulcrumed on a bracket 71 on the stationary Normally the arm 6 lies in the path of the dog f so that when the slidef moves leftward in Figs. 7 and 8 the dog will engage the arm 6 and swing it in a horizontal plane, causing the stem e of the valve 6 to be turned, thus opening the valve and permitting a charge of fuel to pass through the pipe e into the pipe f at a point within the water-tank d. Should the pressure of gas within the gas-receiver be sufficiently great to lift the lever h, the arm e will be raised out of the path of the dogf and the movement of the slide f will therefore have no effect upon the arm 6 A spring a is attached to the casing of the valve e and to the arm 6 and tends to throw the parts e and (2 so as to keep the valve 6 normally closed. As the dogf moves to the left (see Figs. 7 and 8) sufficiently to ride off of the arm 6 the spring 6 immediately asserts itself and returns the arm to the closed position of the valve. A pin 6 is fastened to thepump-cylinderf' tolimitthe return movement of the arm 6. The hollow valve 9 has rigidly connected thereto a stem g which extendsupward and carries fixedly an arm g, projecting laterally over the slide f A spring g is connected to the stem g and tends to throw the same, together with the valve g, to the position shown in Fig. 5, in which position the port g registers with the pipefand the ports 9 and b are out of communication. The arm g is adapted to be operated by the dog f When the slide f moves rightward, (see Figs. 7 and 8,) the dog f will engage the arm g and throw the arm in the manner indicated by the dotted linesin Fig. 7. As soon as the pawlf moves past the arm 9 the spring g will assert itself and throw back the arm to the position shown by full lines in Fig. 7, causing the ports of the valve to occupy the positions shown in Fig. 5. A pin 9 is mounted on the cylinder)" to limit the leftward movement of the arm 9. The valve g carries an electric igniter. One

terminal of the circuit is in connection with the body of the valve and through the medium of this element with the stem The lower end of the stem 9 carries a contact 1'. Fastened in the valve g and projectinginto the interior thereof is an insulated plug 11', which carries a contact 1' at its lower end. This plug 7." is in connection with the other pole of a source of electrical energy. The plug 2" is arranged to turn within the valve g. At the upper end of the plug 2", above the valve g, is an arm i which is fastened to the plug. This arm is held at its outer end by any suitable guide device '6 (See 7.) This guide device I have here shown as composed of two guide-rollers bearing on opposite sides of the arms i and adapted to be supported in any suitable manner. For example, they may be supported by-brackets projecting from the water-tank d or from the section b of the receiver.

The parts thus constructed operate as follows: As the shaft 0 turns the piston of the pump f is driven and a blast of air is forced through the pipe f. As the slide f moves leftward (see Fig. 7) the dog f strikes the arm c and throws the same, so as to open the valve 8 A charge of fuel passes through the pipe 9 into the pipe f, and then as the piston of the pump moves rightward it compresses a volume of air and forces it through the pipe f. The charge of. oil is thereupon vaporized within the lower portion of the pipe and the hollow valve g, the parts being in the position shown in Fig. 5. The instant this occurs the dog f strikes the arm g and throws the hollow valve 9 to the position shown in Fig. 6. This cuts off the pipe f and opens the port If. As the valve 9 turns it carries the plug 2" around withit, .and this causes the contacts t; and i to come together, thus producing the spark which i,,- nites the charge within the valve g. The explosion then takes place. Instantly after this period the dogj' rides off of the arm g and the arm g returns to the position shown by full lines in Fig. 7, placing the valvegin the position shown in Fig. 5. The operation above described is then repeated. As the explosion takes place the receiver is filled with the expanded gases and the section 12' yields outward. The instant this occurs the port I) is closed and the gas-pressure is forced to pass out of the pipe 0, thus driving the wheel 0 The pressure within the receiver is continuall y replenished by the successive explosions, and thereby a uniform and steady gaspressure is communicated to the wheel 0 Having thus described my invention, I
